My Droid Turbo 2 has been loosing its battery very rapidly lately, and has also started to overheat. I'm not sure whats going on with it or why its doing this, and I've been looking for solutions online and finally I am here, making my own thread because nothing seems to be working or related to my issue.
A lot of other users reported massive battery usage after the Android N 7.0 update, and that's where I started my research. I haven't noticed any significant battery drain after the Android N update, but after the security patch that just came through I am finally starting to see some issues.
After taking my phone off its charger (I use a wireless charging pad), within 5 minutes I was down to 97% battery. The entire day I have been watching the percentage tick down pretty rapidly. According to the battery page, I've had the screen on for 1 hour and 28 minutes and I'm at 58% battery. The screen accounts for 11%, cell standby for 6% and phone idle for 5%.
I use my phone very lightly throughout the day, I do NOT have the Facebook app or the Messenger app installed, and I cannot figure out where the battery drain is coming from. When I have the screen on, I'm usually around half brightness most of the day unless I'm in direct sunlight. When the phone is on, within 10 minutes the back starts to get pretty warm, and I can watch the battery level drop pretty rapidly. When the phone is off, its cool to the touch and holds its battery level right at the percent where I left it at.
According to the Android battery page, I have 8 hours left with 58% battery, which I don't think is accurate at all considering I can watch the level drop as I'm using it. I installed Gsam Battery monitor and I'm going to let it run throughout the day tomorrow after it charges up tonight.
I usually have the phone on the wireless charger every night and take it off around 7AM. I used to get a full days use out of the phone with plenty left over, but not anymore.
Here's the "fixes" I've done so far:
Factory reset (clean start)
Wiped cache partition from recovery
Disabled WiFi and Bluetooth scanning
Set WiFi to sleep when device sleeps
Put location settings to battery saver
Did the "reset app preferences" from the battery menu
Set the cellular preference to LTE\CDMA
Any help, or should I inquire about a replacement phone?
Those numbers seem high. Might be worth a call to LenoMoto or a trip to a store.
Also, leaving wifi on during sleep might lessen the cell stand-by.

I had shut that off in order to hopefully conserve battery, still no luck. No Motorola stores in my area, so I'll have to call.
Unfortunately my warranty ran out in May........I wonder if they will make in exception since its not that far out of it?
I was thinking VZW store.
Tried attaching a screenshot of my Batt screen, no wifi at the station and week cell signal.
Doesn't hurt to call.

Getting on the phone with them now.
How has your battery held up for the time you have had your Turbo 2? Has it ever lasted you anywhere near the 48 hours its marketed as?
I can get 24 hours depending on usage and location. Never got 48 hours.
Generally weak cell and wifi are my biggest drains.
I have a Samsung S2 smartchwatch and the Sammy app is a bit of a drain.

Weak cellular signal can drain the battery faster than a strong cellular signal? Never heard about that before.

Yup, radio in the phone is essentially working harder trying to pull a weak signal.

And keeping the WiFi awake during sleep can fix that?
After a lengthy conversation with Motorola, here is the diagnosis from them.
Because I have been using a wireless charger, they don't believe its been supplying the correct voltage for the phone to properly charge, and therefore wont hold a proper charge. The charger I have is a wireless one by Anker and supplys 5v at 1.0 amp compared to the Motorola Turbo charger which supplies according to the back of the plug
Standard output 5v at 1 amp
Turbo 1: 9v at 2.85 amp
Turbo 2: 12v at 2.15 amp
I'm guessing mine is the Turbo 2 (duh?)
Here is what they suggested. They want me to charge the phone using the turbo charger tonight, and install GSam battery monitor and use the phone like I normally would tomorrow. At the end of the day the Gsam battery monitor should be able to tell me if there is something system based or app based that is killing the battery.
So that's the plan for now. I completely forgot to ask them about a replacement phone since its not that far outside the factory warranty, but hopefully my issue has just been an improper charger this entire time and I haven't bothered to notice the crappy battery life up until now. I just hope the useage of a wireless charger hasn't caused any permanent damage to the phones battery.
I'll post back once I have some results tomorrow night, and I'll post up some screenshots.
I keep wifi on during sleep for that and to save data.
Interesting diagnosis. 2nd time I've heard that about wireless chargers and length of time the phone holds its charge.
Doesn't make sense to me the 2nd time either.
If the phone says its charged to 100%, then why wouldn't it be charged to 100%?
How does the rate of charge effect the rate of discharge?
I use a wireless charger at home at night and the original Moto T2 turbo charger at work at night. Never noticed a difference in rate of discharge during the day.
I've also used GSAM periodically to chase drain and haven't found it too useful without root.
Now that I think of it, I turned Moto Voice off months ago. I don't miss it much. That did cause more drain.
I also disable or uninstall any apps I don't use.

I have heard about improper chargers causing issues with phones in general, nothing specific to the Turbo 2, but I guess anythings possible. I have also heard about one of the bad side effects of wireless chargers is that they generate quite a bit of heat sometimes. Since mine is only on the wireless charger when I'm asleep I can't confirm nor deny that. I could definitely see how if you charge up a battery and it gets hot, as it cools down the capacity diminishes also (sort of similar to blasting air into an SCBA cylinder rapidly so it gets hot as hell, then when it cools you only end up with half the capacity you thought you had) so in my head I could see how that could translate over to a phone battery in some weird way.
Gsam now has a work around where you can use ADB from your computer to grant it the same permissions it needs on a non rooted phone, I just did it today and it worked.
I had a strange suspicion that Moto voice may have been a culprit, I only recently started using the hands free driving to announce texts and calls and allow you to reply by voice commands part of it since NH passed the hands free law. I shut that off today, so I will see if that makes any sort of a difference tomorrow. The only other part of the Moto features I use are the gestures (twists, chops, etc.)
Aside from that I also use the Google Smart Lock feature to keep it unlocked when I go home, but I've used that since I got the device and it hasn't caused any battery problems. I keep the location service in the battery saving mode.
I only have apps I need on my phone, and I have disabled 99% of the Verizon bloatware excluding the MyVerizon app.

Took it off Moto Turbo charger around 02:00 when we went on a call. Didn't plug it back in when we got back.
Been outside the last 2-3 hrs doing yard work and streaming Pandora. Batt at 60% and estimate of 19 hours left.

Here is where my phone currently is at. Took it off the charger around 9AM and have been using it fairly light since. According to the doze menu it is going into its proper sleep mode, but it still does drain incredibly fast when I am actively using it.
A lot of the drain is coming directly from Android is and Google services. I'm not sure why.
Here is my tablet for a comparison. The tablet is an Nvidia Shield K1, which is not known for its battery life at all due to the fact its designed for gaming and performance. Its inky rated for around 4ish hours of constant game streaming and around 10 hours of standby time.
I'm up to 1 day and 3 hours with 30% remaining, which is insanely good for this thing, so the Android Doze is working. Android system and Kernel are also at the top of this list, but have far less active time.
Also, on my Droid I disabled the moto quick notification glance, thinking that was keeping of from going into doze.

Another question, what is your screen on time? I'm at 63% at 1 hour of screen on time which seems like way too little to have drained so much (24% from the screen at half to 3/4 brightness.)

2 hrs -14 minutes now, but this is several hours later and I had it sitting on the pad for about 20-30 minutes or so, my stats for the rest if the day aren't valid.
I have it around 40% with Adaptive Brightness-on.
Looked like you had twice as many wakelocks on your phone compared to your tablet.
I don't know enough about GSAM to interpret it effectively. Hopefully someone else will chime in.

So I'm up to about 2 hours of screen time on mine with 41% remaining 12.5 hours total.
That's actually really disappointing considering everywhere else I read, people are posting anywhere upwards of 5+ hours of screen on time with between 60 and 70% of their battery remaining.
According to Gsam, 30% of my loss is through apps, the top 3 being Google play services, kernel and Android os.
Google play services and the Kerbel have both kept my phone awake for close to an hour each. can't figure out what is doing that with kernel, but Google play wakelock reports show something called
NlpCollectorWakelock as the #1 culprit at 40.3 minutes.
The Phone radio accounts for 23% of the loss as well. Im not sure if that's because of a low signal but I attached a screenshot.
It still sucks being able to watch the battery percentage drop an average of 1% every 2 minutes, since that's 44% of my loss. I posted a screenshot of that too. I usually have mine around half brightness with the adaptive on.

I remember you mentioning that now,
This is what my cellular chart looks like. Perks of living in a small town.
Still don't see why that would cause things to drain super fast with the screen on, because it seems like it's standby power is holding up fine. Earlier today I locked the screen at 70%, 3 hours later checked my phone for the time and it was still at 70%.
Another interesting find, you had mentioned my tablet didn't have anywhere near the same amount of wake locks as my phone. I just checked that again and here's what I found.
Tablet: Wakelocks from NlPCollectorWakeLock - 160, keep awake time for 9m
No NLPWakelock
Phone: Wakelocks from NLPCollectorWakeLock - 837, keep awake time for 41.7m
NLPWakeLock - 3869, keep awake for 5m
Total keep awake time from google play services
Phone: 51m
Tablet: 19m
That's just google play services however. Kernel and Android System are account for way higher battery drain, but only the Kernel has a keep awake time of an hour, Android system is only 5 minutes.
Doing another factory data reset, this time I'm going to install anything on the phone at all except the necessary updates, just to rule out the possibility of a app that's killing the battery. If it still drains rapidly after this, It either has to be a bug within Android or Google Play Services or faulty hardware.
After speaking with Verizon the best they where able to offer me is a $150 replacement.

sucks. I know there are threads about this but I just am sick of this. I had the Evo for a bit and I swear that battery life was better.
I don't know if its because of my crappy reception or what--but I can't even last a morning of light use with this phone. Super annoying... I had high expectations but when i'm getting low battery warnings before noon with barely using the phone at all, something has got to be wrong. I did a factory reset, did a full discharge/full charge. after it said fully charged i unplugged and plugged back in. i don't know what else to try. should i replace my phone? ask for a different battery? the date on the battery is 8/14.
Ok my rant is over...publicly that is.
edit: mods you can just delete this thread. i also hate clutter and hate that my rant has added to it. (hopefully we get some sort of update/custom rom soon that fixes battery!)

The battery life on my EVO is not better.
What do you do with the phone that drains it so much?
Open up your battery statistics. What is using it the most? How long is your display on for (select "display" from battery history and it will say long long it has been on for).
Have you charged it correctly for 1st time use? (charge to 100%, then drain to 0, then charge to 100% again)?
Seems like you are experiencing much faster battery drain than expected. My battery lasts all day long with light use (~22 hours). 10-12 hours under heavy use (3-4 hours of screen on time). I use juice defender as well, and I keep my screen brightness at 0% (still pretty bright) unless I go outside).

i've done everything you said. this isn't my first smart phone.. i've been around a long time. :-/. from what i have been reading some have been getting the ok battery life while others are in the sinking boat with me. just frustrating..i've been giving it more than one chance since i got it at 8am 1 week ago.
Bro turn off wat u don't need. Auto sync is adrain and having data connected is a drain as well. If ur not using the data then turn it off. U can still txt n get calls. N when u wanna check the net or watever then turn it bak on.

In Battery Usage / Cell standby, what is your time without signal? If it's high (like over 10%) this will eat your battery, so you'll need to reset the radio by quickly going into airplane mode (hold power) and leaving airplane mode. TWS will drop quickly. Weird bug, you'll have to do this once every reboot, hope it gets fixed.
Also, if you are in an area like work or home that has wi-fi, leave it always on, turn off "notify open networks" and hit Menu / Advanced to switch the wi-fi policy to "never sleep". When you are at home or work the phone will auto connect to these places and do all data over wi-fi which uses less power than 3G, even when the screen is asleep.
Finally, while I leave on window animations & Google Talk, I turn brightness in the browser and on the phone all the way down and turn off haptic feedback except for the capacitive buttons.
I've been unplugged since 8:30am and have been at work & home and texting all day, light surfing, a few phone calls, apps, etc, and now at 10pm I have 65% battery remaining. I think that's pretty good.

Wha?! All that and still 65% by 10pm? If I let my phone sit on the desk from 8:30 am by 10pm I would probably be less than 65%.
The range of experiences is just way too wide on this board. I like this phone so much that I've decided to just accept it drains battery and have chargers everywhere. Plus I have 2 in my house purchased in different stores that exhibit the same power consumption.

You wanna explain this to me? Do you mean ALWAYS have wi-fi enabled? Or just when I'm at home? I use wi-fi at home for both the better battery life and faster speeds, but I was under the impression that if I always had it on that it would always be searching for signal, thus being entirely counterproductive.

This. I don't have all the chargers yet, but come Friday, I'll have two house chargers, an extra computer cable (for school/work), and my car charger. This phone is too awesome to let my battery life ruin it.
I've noticed that web browsing kills it fastest, which wasn't a surprise at all. I usually get 8-10 hours out of it, which is a lot lower than desired, but something I can live with. At least if I get my chargers, I can save the overall life of the battery.
Another thing to mention:
Vibration, while convenient and least annoying to everyone else, is the most power-draining notification you can use. Next is audio. Last is silence (obviously). Having it make noise AND vibrate is like signing your battery life's death warrant.
i think hydralisks epic runs on fairy dust and unicorn blood bc my epic sucked battery like no other.. and thats...screen brightness at 0...no programs running at all. and it still said 77% of battery drain was from the display. lol

First one reads: 21 hours and 29 minutes. For almost 4 hours of that, the screen is on. So you people saying you get 5 hours of battery life are doing something very wrong... or you have a bad phone. I can easily surpass 4 hours battery life with the screen on the whole time. Some of you don't seem to realize that once the phone hits 10-15%, it takes a LONG TIME to get it down to 0%. This is probably due to the battery just not being calibrated yet. At 6% battery I actually had to watch a whole hour of movies to get it to 0%... and even then the phone did not shut down.
Edit: phone was in airplane mode because the battery was at 0% and I didn't want it to crash before I snapped the photos. Cell standby is a major killer of battery. A solution to that (if you have a large cell standby number) is just to toggle airplane mode on and off when you boot up your phone. It works... dont know why. By my cell standby is almost always down to 5-10% now. More info on this issue here: http://forum.xda-developers.com/showthread.php?t=772571
i agree with hydralisk, try toggling the airport mode on and then off. it will reboot the antenna of the epic. the cell standby mode totally drains the phone's battery reguardless of user activity or not. mine was 51% without signal but after the airport mode toggling, it dropped down to 8% without signal and my battery is somewhat better. (i'm a hardcore user so 8-10 hours is awesome for me. haha)
I can say that my first Epic was a bad phone. It wouldn't even last 3 hours on a single charge! It would discharge while browsing amazon.com and bn.com using the built-in browser and while plugged into the AC charger. I thought I was seeing things.
Today, I've exchanged it for a 2nd Epic. It still does discharge when I'm pounding away on it even though it's plugged into a USB charger. But otherwise, everything else is looking at lot better now, especially AC charging.
So there are good and there are some very bad examples of the Epic out there. I believe I've personally had my hands on both kinds.

I'm getting great life with the latest rooted kernel by noobl. 5 hours and phones at 98% medium usage
i am getting similar hours to hydralisk.
i love this phone! it looks like there may be a few bad apples in the bunch, but i hope everyone else who got a good phone is enjoying it as well!
I got my SGSII on Sunday and I am extremely pleased with it. Its like the phone of my dreams in almost every way. It's responsiveness, its camera, its form factor, its screen, everything about it was great. Until I noticed that the battery was being drained kinda fast. I rooted it within a day and tried every ROM available so far but none of them alleviated my battery issue. I've read and tried every solution on these forums but nothing works.
I lose approximately 10 percent of battery every 30 minutes and have gained a maximum battery battery life of 8 and a half hours. Ive Frozen most of sammy's bloatware and have optimized it as much as i can. i disabled fast dormancy everything.... I just dont know what to do.
Did you try restoring original Samsung firmware, factory reset with full wipe, and then doing initial setup prior to getting on wifi?
Try this, don't config any account besides google, don't install any software and certainly don't freeze any apps. Monitor phone for a few hours and then post screenshots of Battery Use app for us to see.
I get about 15+ hrs worth.of battery.
With heavy exchange (push) email and quite a few apps.
My problem is random reboots especially when playing music.

Give it some time. Battery life improves quite a bit after some discharge cycles. Do a factory reset and reinstall as some have mentioned above.
And remember some apps can cause the OS to misbehave.
That's the reason I sold mine. Battery life was unacceptable. Other than that, perfect phone!!! Still looking at this forum hoping for solution to battery problem. Would definitely buy the device back then.

Did you try restoring original Samsung firmware, factory reset with full wipe, and then doing initial setup prior to getting on wifi?
Try this, don't config any account besides google, don't install any software and certainly don't freeze any apps. Monitor phone for a few hours and then post screenshots of Battery Use app for us to see.

Thanks for the advice first thing in the morning ill flash KE7, which is what my phone came with, and report back with screenshots and after a few hours.
Any smartphone battery need at least a good month before reaching the maximum potential.
Just wait a couple of days and use custom kernel with SetCPU.
My ex-Arc did the same, first day battery droped 7% every hour on idle but after a week battery could last 3 days
if u continue in this topic its very better. 1 topic about battery is more better

For me, it's simply because i'm battering the phone with internet use, and generally playing around with it constantly all day while at work.
I get a full day, sometimes two now, depending on how I use it.
My old HTC Desire used to need charging twice a day, until I got my SGS 2, now the Desire needs a charge once every 3 or 4 days, due to the fact I am playing with my new toy! lol
I'd say battery life will improve as time goes on and usage of the phone goes from all day, to normal smart phone usage
In all seriousness, the SGS two outlasts my Desire easily, which is good enough for me. I struggle to kill the SGS 2 in a day.
If you are losing 10% per half hour, is that with the screen on? If so, that is fairly normal. I find that 5 hours of screen on time is the most you'd normally get. If its in standby mode (screen off) and you are losing that much per half hour then something is wrong.
Those you of who are getting amazing battery life, would love to see a screenshot with more than 5 hours screen on time - just to see if it is possible. 3 or 4 days means nothing if its in standby 99% of the time

Yep, how you use the phone is huge. Screen brightness and many other factors like installed apps and what they are doing can have a major impact on batt life. IMO battery life is almost impossible to compare except your own in static usage after making changes. Even idle batt life is effected by push email, weather, etc. In my own usage I was getting poor battery life to start with (multiple charges per day) or was I? There I was screwing around with the phone constantly. Loading this, uninstalling that, taking browsers for test drives, trying launchers, flashing roms, seeing how different games played, showing other people the phone, and so on. The excitement wore off and I got to normal usage (for me) which since I unplugged 17 hours ago is 18 texts, 7 calls all of which were short, and assorted stuff like doing a search, a little web browsing following the search and so on. I'm at 61% showing on batt and my largest user was screen with 59% and then OS with 11%. So this is pretty obvious, cant make it through the day hammering the phone but no problems with what I think most people would consider light usage. Where I'm going is that I think some people may not realize how much they are using their phones in their wahoo new phone frenzy.

Quoted for truth! With normal daily usage about 12-14 hours off the charger you'll see 5 hours of display at the most. GSMArena has done some tests and in airplane mode playing a video on loop on 50% brightness can last a bit over 8 hours. Once you add in having to maintain a cell signal, wifi, push email, idling for another couple hours, it reduces your possible screen time in favor for those other activities.
The best ways to conserve battery are to make sure you don't have rogue apps that are keeping your phone awake when it should be sleeping. Check your battery graph and actually CLICK on the graph to expand it to check if your "awake" bars line up with your "screen on" bars. If they don't, something is wrong and you have to find out what's causing it to stay awake. If you've been browsing (white) websites on wifi for 5 hours and complain when the phone says low battery... tough. You're using the display, wifi, maintaining a cell signal, as well as viewing sites that strain the SAMOLED display the most - white backgrounds.
Based on my experience, my battery life is actually quite good. After 4 hours of idling and only about 20m of display on (auto brightness) I'm still at 91%. After a day's use with about 1h of screen time and 14 hours off the charger (about my avg workday usage) I end up around 65-75% which I consider not too bad and can definitely go 2 days on my average usage. Basically minimizing the battery draw when the screen is off is key since when the screen is on, nothing can stop it from draining the battery.

Mine,
From 100% to Full drain (Switch Off). Total usage 1d 19h. At 20% Brightness. On XWKE8. More than 5 or 5½ hours is NOT possible, whatever you do. It's not that I am impressed with it, 5 hours isn't enough, 7-8 hours would be good though
Regards.
Well i left my phone idle for approx. 5hrs and im dwn to 63% but now im noticing a problem that i havent noticed before... my Android OS is now taking up 38% with which is more than Display which only took 21% and the phone was constantly waking up. I have no apps runnin in the background nothing else out of the ordinary.

You must have SOMETHING that is eating up the CPU. If you are out of guesses, do a factory reset with data wipe, restore original firmware (if you flashed a custom rom), do another factory reset, configure only gmail, and then monitor the battery usage. It would be losing at most 2% an hour in standby. For me it was 1% every 2 hours (with absolutely nothing running except google) when I tested. I the slowly added my apps making sure I do not install crap and do not configure osmething to always do some **** I do not want.
I don't understand these "battery life sucks" threads.
I have an Unlocked SG2 with stock ROM. It is not rooted, I have not frozen any apps. I have four exchange accounts syncing on push, social networks up and running and widgets on all of my screens. I text and check e-mail frequently throughout the day and I use the camera here and there.
I always get at least 15 hours out of my battery, if not more. For comparison, I was using an iPhone 4 under the same conditions (with the same accounts syncing) minus any widgets or automatic social updates and I was getting roughly the same battery life.
No, this phone won't last you a week with heavy use, but you should easily get a day out of it and I rarely find myself in a situation when I can't charge it overnight. This phone is on par with all of the best battery life smartphones out there, as far as I'm concerned. Those of you getting horrible battery life should probably look into an exchange or maybe an app you recently downloaded. The only time I got really bad battery life was when I ran a live wallpaper that was pegging my CPU.

Before going to sleep do these things,
A- Check if 'Auto Sync' is running, Disable it if it was. Same goes for Background Data, Disable it.
B- Go to Task Manager and see if any Apps are running. Close it if some were.
C- In Task Manager, go to RAM tab, Press Clear Memory, it should close the hidden apps were running. ***DO NOT do this if you have some kind of Scheduler application running, it will NOT work then***
D- Download an app like Auto Task Killer.
E- If possible keep the 'Power Saving Feature' on with your desired settings.
Do these first, if not worked, do a Hard reset. For me, it decreases about 5-6% battery (max) in overnight period of 8-9 hours.
Regards.

I'm not sure what you mean by "battery backup". Are you referring to standby time? Yes, the iphone does better in that department, but that's not typical daily use. Phones are meant to be used, not sit around for days at a time. Iphone can do this because it doesn't truly multitask and no data is syncing. Either you have a faulty device, bad Rom, or your expectations are unrealistic .
My Battery drained from 100% (it was fully charged, then I unplugged it and locked it) to 75% overnight.
What are some likely causes of this?
I noticed you have no signal. Constantly searching for a signal will drain the battery...
I've only had my N4 for a few days but the battery life has been good so far. A couple of brief observations...
1) On wifi only overnight (no SIM as I just got it and didn't have a micro yet) for 7+ hours. ZERO % drain...
2) On LTE (2-3 bars) for the past 3 hours. I left the phone and came back later. ZERO % drain...
Gmail is push, no GPS or BT. Only core apps running. I don't normally have anything in the back ground outside of lightflow...
Download GSam battery monitor
I noticed this also. I never had that much drain with my Galaxy Nexus.
I went out to lunch. Sent a few texts with google voice and looked up some random food articles on wiki for a few minutes. I was gone for 1-1.5 hours and now my battery is down to 47% from 75% this morning.
I'm going to download GSam and see what I get from there.

Your android OS usage is terribly high. That's my first suspect.

My android OS usage is very high as well... sometimes higher than the screen. I'm gonna try turning off google now to see if that does anything but other than that I have no idea what would be causing that...
The screenshots show app usage as being 50%+.. It is probably a rogue app you have running in the background.

I had the same issue for a couple of days. I would wake up to my phone only having 65% charge and the device would be rather warm. In my situation, I found that the charger was faulty. I noticed at times it would cause the phone to flicker back and forth from charging to in use. Lucky for me, I don't sleep well at night and I found the issue after my phone had been plugged in for 5 hours in the middle of the night. With that said, I also noticed the charger would make a high pitched hum/hiss. I swapped my charger out for my old Iphone 4 charger and I haven't had an issue.
Nearly a full day's results.
I left my phone charging from night until morning. I unplugged my phone sometime around 10-11am and I stepped out around 12:30.
It's 5:52 pm now.
I was out from around 12:30 to around 5ish. At around 5 my phone had 50-56% battery left. My friend's Iphone 5 had 75% left. Aside from my friend using his iphone as a GPS to navigate in the car (around 20 minutes) - we had roughly the same phone usage (by my estimate of course), we were at same locations and both of us are on the same network.
To be frank, I don't understand why my friend had more battery life than I did considering he was using gps. I do feel like there is something draining my phone battery.
My screen light settings are on automatic.
I've attached GSam and my list of applications.
From about 5 to now (5:52):
After a bit of surfing, installing 1 application to list my apps, emailing that app list to myself screenshotting the relevant data and emailing those screenshots to myself over wifi. I'm now down to 39%

9:12
3 hours and 20 mins down the line.
I'm at 10% battery.
I figured we could get this started, so we can start to post stats and screenshots once you finish initial setup/installation and get into regular daily use.
went to bed last night with the idol at 75%. woke up and it was still at 75% to my surprise. (and I did the update right out of the box, for anyone wondering.)
Seem to be great, can't wait fort mine
The phone arrived at around 40-45%. Spent around 2 hrs updating/installing/customizing stuff which was enough to drop the battery to 15%. Mind you that almost all factory settings were still there like vibrate on almost everything and sound on almost everything. Battery was fully charged rather quickly. I had around an hour of SoT before going to bed with around 80-75%. I woke up to a 70% battery after 10 hrs ( I slept in).
I think battery on mine could be improved by turning down the Google Now settings. It is the most power hungry in the battery stats at 9%. Oddly, the location icon is almost always on even if I'm not doing any location related tasks. I'm hoping to look into this more and fully test the battery tomorrow when I go to Sta. Cruz.
The Idol 3 just won't die! I'm using it around the house. Haven't actually put a sim card in it yet, so that might explain some of the great battery life that I've been getting. But this is the first full power cycle after getting it on Saturday. Auto brightness, full sync. I had to stop at 11% so I could do a charge test today. But I have no doubt that this 11% could have gotten me another hour of screen on time. Tons of streaming Sirius too over the front facing speakers (like 5 hours). Very impressed so far. The price is justified by the screen and the speakers alone in my opinion. Add great battery life to the mix and it's a pretty special device IMO.
Charging time is done. Used an Anker 2.0 Quick Charge (just to make sure it got the maximum it could handle). Went from 11% to 100% in 2 hours and 28 minutes. Not too shabby considering how long it holds on to the charge.
Bettery drain while on wifi
Hi, I have bad battery drain while on wifi. What I noticed is that cell signal goes from empty to full while unlocking screen. It goes up to 10% per hour. But when I was away from home for few hours on lte, it was very minimal. Any ideas? Software bug or maybe some app is causing that? Thanks!

I should have checked the battery life before loading all my apps but I forgot. During sleep hours I only have the wifi, auto sync and phone antenna enabled. I also either use the adaptive brighness at 50% or have the brightness set to about 20% with adaptive disabled. The first night I checked the battery overnight usage it was down 16% in 10 hours. That was also runny 3 apps on the notification area. The drain comes to 1.6% per hour. The next night I removed the 3 apps that run in the notification area and the drain was 10% in 8 hours, which comes to 1.25% per hour. That's better than my old phone but I still think it's too high. No apps are open in the recent apps screen.
Is anyone getting better or worse? I would like to compare my battery drain with everyone else.
Edit: I did disable Wifi Network Notification and Scanning Always Available. I'm not sure what kind of effect they have on the battery though.

Yesterday was my first battery experience day. I have to say it turned out pretty good. I got roughly 16hrs from 100% charge down to 15% charge. I got a battery warning when i was headed to bed. Throughout the day, here's a list of the things I did in general to give a scope on usage:
* I had all services on, LTE, Wifi, Bluetooth, GPS (High precision)
* i used it to read a kindle book. I had my screen set at about 80% brightness the whole day.
* I have "Automatic" app which uses the phone GPS to track my drives to and From work.
* I ran with Runkeeper GPS
* also streamed music to and from work on my wohle commute (roughly 45 minutes).
* Then throughout the day did normal checking of various apps and websites, and notifications.
* In general during the work day I don't use it much from 9-5, except maybe to check it once an hour , and read a little.
Previously on my Nexus 4, I would have had to have it charging all the way to work. Then charging all the way home, and many times it wouldn't make it to bed time without another charge. With the Idol 3, i didn't put it on a charger once throughout the whole day. Pretty awesome.
This is my second full day. I expect that it will improve after a few cycles but I have absolutely nothing to complain about. WiFi on most of the day. 2 Gmail accounts syncing, Bluetooth on, display only at 50%, (not to save battery, but just because I don't need it any higher)
I have a few small hiccups with the DTTW but it isn't terrible.
P.S. This blows away my Zenfone 2 in battery life.
Battery life is ridiculously good. Charging my phone is no longer a pressing issue for me nowadays. Personally, I am indoors most of the day so I have set my screen brightness to 0% and it is perfectly fine. When I am outdoors, I will pump up the brightness to 100% which increases the battery consumption noticeably.
I've had the phone for a week and a half and still have never gotten down low enough for Battery Saver mode to kick in.
For me battery hold amount of charge EOD.
100% in morning around 10 AM.
1. wifi/4g ON all the time.
2. GPS during commute to work and vice-versa
3. Music app for 1.5-2 hrs.
4. played game for 2 hrs.
5. normal browsing.
Now @ 7 PM : still 45% left.
For those still unhappy with the battery life here are a few free apps that can help:
https://play.google.com/store/apps/details?id=org.gpo.greenpower&hl=en [ Battery saver...does things like only keep wifi on periodically to check for hotspots and only turn on bluetooth when charging etc ]
https://play.google.com/store/apps/details?id=com.vitocassisi.luxlite&hl=en [ Adjust screen brightness based on light levels ]
https://play.google.com/store/apps/details?id=com.keyes.screebl.classic [ Keeps screen on when phone is held in upright position but quickly turns screen off when phone is placed flat ]
I use the pay versions of these and consider them worthwhile.
Does anyone know how the automatic brightness works or if its even useful to have it on

So Doze is supposed to minimize battery drain to almost nothing overnight or when the phone is not in use for a long time. How many people have actually experienced that? I'm not sure what to think, I lose about 1% per hour consistently overnight. That's without greenify or other battery saver methods. But it still seems excessive to me for such a hyped feature. I wonder if future hacks will be able to turn doze on in 1/2 hour instead of 1 hour. What have your experiences been?
1% per hour is pretty good. That means your phone would stay on for up to 100hrs which is more than 5 days. Are you complaining about that?

Doze only dozes applications from waking up the phone at their will, but still does periodic wakes. It will only make a big difference really if you had a misbehaving app in the first place.
Don't forget that even in the best case that Doze stops all activity from apps, you are still using power connected to the cell and or Wi-Fi, plus power to refresh the memory and other peripheral chips, so 1% an hour could be considered quite good.
Try putting the phone into flight mode over night and see if that 1% drain an hour goes, if all is well you should get around 1 or 2% power loss in 8 hours.
The other think to note is apps can bypass Doze and schedule wakeups regardless, this needs an update to the app for Marshmellow. So if you had an app that wanted to wake the phone every 10 minutes to download the latest adverts, it will stop under Marshmellow when Doze kicks in, but they could update their app to use a different API call and go back to waking the device every 10 minutes bypassing Doze. I strongly suspect that the Google Play store will start recognizing this API call and may start warning about apps that are battery drains, so the user can make a better decision, otherwise Doze will have a short term benefit as apps work around it.
Regards
Phil
Doze is working really well for me. Battery drain overnight seems to almost be non existent. I went to bed with 51% battery life on my phone. I woke up roughly 7 hours later and it was still at 51%.

Doze only dozes applications from waking up the phone at their will, but still does periodic wakes. It will only make a big difference really if you had a misbehaving app in the first place.
Don't forget that even in the best case that Doze stops all activity from apps, you are still using power connected to the cell and or Wi-Fi, plus power to refresh the memory and other peripheral chips, so 1% an hour could be considered quite good.
Try putting the phone into flight mode over night and see if that 1% drain an hour goes, if all is well you should get around 1 or 2% power loss in 8 hours.
The other think to note is apps can bypass Doze and schedule wakeups regardless, this needs an update to the app for Marshmellow. So if you had an app that wanted to wake the phone every 10 minutes to download the latest adverts, it will stop under Marshmellow when Doze kicks in, but they could update their app to use a different API call and go back to waking the device every 10 minutes bypassing Doze. I strongly suspect that the Google Play store will start recognizing this API call and may start warning about apps that are battery drains, so the user can make a better decision, otherwise Doze will have a short term benefit as apps work around it.

that was a great explanation, also I do think 1% per hour is bad since like someone already stated that I've had phones that would drain about that without marshmallow. Also those other people who replied I would really like to know how you get such little battery drain, do you guys have a lot of apps installed? I unplugged today around 5 am and woke up around 10 am with 95%. I have about 60 apps and 3 email accounts (1 yahoo which is set to sync manually).
Personally I am trying to sort my battery issues with this phone as some are getting great battery life (5 hours sot with over 24 hours off charge) while others are barely hitting 3 hours like me. Also I would think doze would be better than what I am experiencing.
How long have you had the phone for? AFAIK it can take a few days for Doze to "learn" how to optimize (reduce) battery drain. You may find it gets better over the course of a week or so. If you check the "detailed" battery stats (click the first battery graph) you should see little to no "awake" time overnight when you'd expect Doze to kick in - e.g see this link as an example: https://drive.google.com/open?id=1wjguaIIcGgUZn7w-KXnY3MJ0qTK0rUCWiA
Otherwise try as @PhilipL suggested and run in aeroplane mode overnight.
Doze is working as advertised here. On my 5x and my N5 as well.

It could be your location and the cell signal you are receiving, sometimes even if you have a good signal you still might be evenly served by 2 or 3 masts and the phone keeps swapping between them, if you don't have too good a cell signal, the phone will be using more power during standby. The only way to tell for sure is to put the phone into flight mode overnight.
One thing to note, you will only get the maximum screen on time if you use your phone a lot, i.e. all the screen on time is used during a 12 hour day after a full charge. If you are only using say 30 minutes one day, 20 minutes the next and so on, your total on screen time achieved will be less than many are saying they get, this is because more power is spent over time on background tasks and syncing, leaving less for actual on screen time. My previous Nexus 5 for example, sometimes I would go 4 days without needing to charge it, but my actual on screen time was only an hour or so.
Perhaps crudely speaking, 1 day of very light usage may see enough battery power expended on back ground tasks to see 1 hour sacrificed of on screen time.
Usually it doesn't matter how many apps you have installed, that in itself doesn't use any battery, of course if those apps are constantly pinging back home to some server, then that is how power is used. Doze will be helping with those apps over night and other quiet periods.

Thats the thing I get about 2.5 hours sot in about 12-14 hours and have to recharge before the night is over. Of course quick charge helps but I really don't want to rely on something like that. Also I'm wondering if wifi calling on will help with battery or will it be like the iphone where it'll just drain more battery? Gonna have to play with it and see what I can improve on. Also noticed that chrome has been using about 15-25% battery on any given day. I do use it as my main browser but that still seems excessive so may try a different chrome iteration if it keeps up.
Thank you to everyone that has helped and hopefully this can be a come all thread for people with questions about or problems with Doze.

What brightness setting, as that can make quite a difference?

Adaptive brightness less than 50%
I'm getting 3 to 4% drain during 7 hours overnight, working well for me.

Hi
Did a test last night, charged the phone to 100%, put it into flight mode and went to bed, checked it this morning and still at 100%.

Now you need to find what is draining your battery overnight when not in Flight mode. I suspect you will find either Google Services or Google Play services not releasing the modem or something similar.
When I installed Cerebus it asked to turn off battery optimization. My guess is that is Doze could be wrong though. It was the only app that asked. So far battery life is better then the N6 that I had a Amplify running on.

That is pretty bad if Doze is on given that 1%/hr is a widely accepted standard pre-marshmallow

Might be a standard if everything worked perfectly, which I have yet to see. With this new architecture, you are guaranteed it. I love it.
I lost about 1% in 3 hours last night with WiFi calling on. Maybe it has to do with poor coverage. Last night I did end up with 3.5 hours sot which I think was my highest. So in the past few days I have factory reset and turned on WiFi calling.
Now I need to optimize my browser usage, chrome was talking more than screen was ~20%. Using #nochromo now and not much better.
Battery went from 66 to 64% last night in 8 hours.. #dozeisdope
